Thanks, Aaron.  Did you see the test-case I sent you yesterday, to
aseigo at kde.org?  It shows that pure Qt has the double-resize problem,
using "qt-copy/examples/widgets/scribble", a main window that has only
a menubar and a QWidget as central widget.  The problem seems to
be where the menubar is created (height 6), triggering a resize, and
again where the menubar is resized (height 30), triggering another
resize.  My patch of "scribble" and the resulting log are attached.

Cheers, Ian W.

PS. I had a look at the QMainWindow code but it is way beyond my
immediate comprehension ... :-( ... so I cannot offer a fix.
